RESUMEN
PURPOSE: To evaluate the impact of depressive symptoms on the subjective perception of quality of life in patients with drug-resistant epilepsy (DRE) after surgical treatment for seizures. Methods: A case-control study with DRE patients who received surgical treatment (n=19) and matched non-operated patients (n=23). We assessed the quality of life using the Subjective Handicap of Epilepsy (SHE) scale, alongside measuring depressive symptoms using the Beck Depression Inventory (BDI). RESULTS: The mean age of the participants was 45 years, with females constituting 52.4% of the patients. A majority (73.8%) had been diagnosed with temporal lobe epilepsy. Those who had undergone surgical intervention showed significantly enhanced performance across all quality-of-life domains on the SHE scale independently of depressive symptoms. The domains of "Work and Activity," "Physical Health," and "Self-Perception" displayed the greatest improvements, with the surgical group's averages outperforming the control group by factors of 1.87, 2.53, and 2.81, respectively. Influential differences impacting the quality-of-life scores included seizure frequency, the quantity of antiepileptic drugs utilized, and the incidence of convulsive seizures. CONCLUSION: The findings suggest that surgical control of seizures in drug-resistant focal epilepsy is associated with improvement in quality of life across various domains, independently of the depressive symptoms of the patients.
RESUMEN
Temporal lobe epilepsy (TLE) is a highly prevalent syndrome among people with epilepsy, and is usually refractory to drug treatment. Structural and physiological changes, such as hippocampal sclerosis, are often present in TLE patients. The objective of this study is to evaluate the feasibility and safety of intra-arterial infusion of autologous bone marrow mononuclear cells (BMMC) in adults with medically refractory mesial TLE (MTLE) and unilateral hippocampal sclerosis (HS). We enrolled 20 patients who had been diagnosed with MTLE-HS and were refractory to medical treatment. All patients underwent a neurological evaluation, magnetic resonance imaging with hippocampal volumetry, video-electroencephalography (EEG) with ictal recording, and a neuropsychological test battery focusing on verbal and nonverbal memory domains. After bone marrow aspiration and subsequent cell preparation, the BMMC were infused by selective posterior cerebral artery catheterization. Patients were followed for 6 months. Safety of the procedure, seizure frequency, neuropsychological evaluation, EEG variables, routine brain magnetic resonance imaging and hippocampal volumetry were considered measurements of outcome. Any serious intercurrent clinical event or adverse effects related to the procedure were reported. No additional lesions and no significant hippocampal volumetric changes were observed. EEG recordings showed a decrease in theta activity and spike density. At 6 months, eight patients (40%) were seizure free. A significant increase in the memory scores over time was observed. The BMMC autologous transplant for the treatment of temporal lobe epilepsy is feasible and safe. The seizure control achieved in this novel study supports the therapeutic potential of stem cell transplants in MTLE-HS patients. Copyright © 2016 John Wiley & Sons, Ltd.
